Wansheng Theme Balck Valley Park

Anyone can please tell me what are the mediums of transportation and how much time it takes for Wansheng Dreams Ordovicians Theme Park/ Wansheng Black Valley Park (Please differencite too if you can) from Chongqing main city? How much it cost for an adult ticket? Is there any student discount? How much time it needs to fully visit the place? Is it worth it?
